For you mathemeticians..

[Mike Kurta]

    Jesse:
    Is there a reason you can't leave the mute for that string in place until your next tuning?  It usually results in a small reduction in volume, but sure saves those trips back to retune.  A formula for overpull would be hard to come up with, and asking the customer to remove the mute might open a can of worms.
